I am a fan of all four tubes you listed. My current favorite has to be the 6L6 though. Seeing how you'll need a dozen, they will probably be the cheapest of the four. They are not the best at low end, but your Vandy's amps will take care of that. The midrange is to die for. Female vocals are just awesome. Stunningly awesome. All the midrange magic of the EL34, but sweeter (to me the EL34 sounds a lot like a 6L6, only much drier). They produce a great 3D soundstage. They do pretty well with rock, hip hop and techno as well. I've had best results from Russian 6N3C (a variant of the 6L6), they are fantastic. The Svetlana 6L6 is pretty good. You might avoid the JJ Tesla 6L6, as it has a compressed sound. I liked it at first, but quickly tired of it. Too much loss of micro and macro dynamics. As Maxgain alluded to, it's very much a personal choice. Good luck and happy tube-rolling!
